CAD functions:
<a href="CAD_using_en.htm">See operating CAD ..</a>

see also <a href="CAD_Base_en.htm#V">Codes Variables</a>

Variables use shortcut key V.

Implicit definition of variables by function VAL():
  Example: VAL(P20 P21)  - the distance between 2 points.

Variables are temporarily displayed as horzontal lines;
  the length indicates the value.

  <h2>V Variable - Value</h2>
V - variable value
Direct allocation of a variable

With Pageup / Page Down key a defined variable.



<a name="F1"></a>
  <h2>V X/Y/Z-part PT|VC</h2>
  get the X- or Y- or Z-part of a point or of a Vector.

# extract the x-coordinate of a point
V20 = X(P20)



<a name="F2"></a>
  <h2>V PT-PT Dist.[Direction]</h2>
  <a href="CAD_Base_en.htm#V">Variable</a> = length between 2 points [into direction]

[Direction]   optional; keine Angabe: direct length between 2 points.
              Distance along a vector: define a <a href="CAD_Base_en.htm#D">vector</a>

Example:
V20 = P20 P21
# distance from point P20 to point P21 into direction Z:
V21=P20 P21 DZ



<a name="F3"></a>
  <h2>V LN      length</h2>
V LN Length
  Variable = length of a Distance

V20 = L20



<a name="F4"></a>
  <h2>V PT - LN Perp.Dist</h2>
PT-V LN normal distance
  Variable = Normal distance of a point from a distance

V20 = P20 L20



<a name="F5"></a>
  <h2>V CIR     Radius</h2>
  Variable = radius of a circle

V20 = C20
